Specification of Letters Patent.

Application filed May 24, 1915. Serial No. 30,251.

improvements in a device for heating and applying coating materials, and more particularly for applying asphalt to surfaces,

which it is desirable to coat therewith.

The object of the invention is to provide a device of the character described whereby asphalt and similar substances may be heated and then applied to objects such as structural steel, pipes and tanks, and in fact any surface wh ch it may be necessary or desirable to coat or paint.

Another feature of the invention resides in the provision of means whereby air or other fluid pressure may be utilized to facilitate the application of the coating.

Other improvements in principle and in details of construction are set forth hereinafter in this specification and in the claim appended thereto, and illustrated in the accompanying drawings wherein:

Figure 1, is a side elevation of the device. Fig. 2, is a plan view thereof, and Fig. 3, shows a sectional view of the discharge nozzle.

Referring now more particularly to the drawings, wherein like numerals of reference designate similar parts in each of the figures, the numeral 1, refers to the tank, which has the furnace 2, constructed in connection therewith, all mounted upon a suitable vehicle, whereby the device may be transported from place to place. The furnace may be constructed for the utilization of any kind of fuel desired, but, as shown, is adapted for the useof oil as a fuel. The asphalt is placed in the tank-through an opening in the top which then is tightly closed by the closure 3.

The numeral 4, designates the oil receptacle for containing the fuel oilwhichis conducted therefrom through the conduit 5, and sprayed into the furnace through the fuel nozzle 6, the conduit being controlled by suitable valves, 7. Leading from the lower side of the tank 1, is a connection 8, controlled by the valve 9 attached to which by the swivel connection 10, isa hose or other flexible conduit 11, the free end of which has the discharge nozzle 12, controlled by the valve 13. This nozzle has a long narrow discharge orifice through which the heated asphalt is delivered in a thin sheet and thereby applied to the surface to be coated. This nozzle has a long rigid neck 14:, forming a hand hold, so that the position of the nozzle may be controlled, 'and fixed to the neck is a circular disk or guard 15, which protects the hand from coming in contact with the heated asphalt in making the application.

Leading from the upper part of the tank 1, and connected to the nozzle 6, is the conduit 16, controlled by the valves 17, 17.

An air compressor 17 of any well-known type, is provided and leadjng'from this compressor and communicating with the conduit 16, is the pipe 18, on opposite sides of which and controlling the conduit are the respective valves 19 and 20. A by pass 21, controlled by the valve 22, communicates with the conduit 16, on opposite sides of the valves 19 and 20.

Leading from the pipe 18 and communieating with the interior of the tank, is the pipe 23, controlled by the gate valve 21 and check valve 25, and through this pipe compressed air is introduced into the tank from the compression chamber which forces the liquid asphalt through the flexible conduit 11. Also leading from this pipe 18, and communicating with the flexible conduit 11, is the pipe 26, controlled by the valve 27. On opposite sides of the pipe 23, are the valves 28 and 29, controlling the pipe 18 and the latter is also controlled by the valve 30, located between the pipes 16 and 26. Air pressure is admitted into the tank from the compressor 17', by opening valves 24 and 28 and closing the valve 29 and when the valves 9 and 13, are opened this pressure will force the heated asphalt through the conduit 11 and the nozzle 12, carried thereby and the application may be made to the desired surface, the nozzle being flexible so as to readily conform to uneven surfaces.

It is sometimes desirable to draw off the gas from the tank 1 and discharge the same into the furnace through the nozzle 6, to relieve the gas pressure in the tank and assist in the combustion in the furnace. This ma be accomplished by opening the valves 1; and 22 and closing valves 19 and 20, which will have the effect of opening the pipe 16,

through the by pass 21, Without pennitting direct communication of the air pipe 18, either with the tank or fuel nozzle 6.

In case it is desired to clean out the flexible conduit 11, and the nozzle carried thereby, the valves 9, 24: and 30, may be closed and the valves 13, 27, 28, and 29, opened and the compressed air Will then be driven through said conduit to unclog the same in case it becomes stopped up.

What I claim is:

A device of the character described including a container for asphalt and the like, a furnace arranged adjacent thereto, a flexible tube leading from the container, means for applying the heated asphalt carried by the free end of the tube, a fluid compressor communicating through a suitable conduit with the container, and a conduit leading from said container and discharging into said furnace.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses. Y
